 | DEBT-030 | `HomePage.vue` "확인 필요" section has no real signal source | Medium (2) | Medium (2) | Completed (Framework) | ✅ **Framework Ready (2026-08-11):** HomePage.vue updated with AttentionItem interface, rendering logic, severity-based styling. Template renders dynamic list when `attentionItems` has data; empty state when none. Implementation guide created: `frontend/src/features/home/DEBT-030-ATTENTION-ITEMS.md`. Next step: each feature (model-operations, sell-decision, data-quality, portfolio) provides `useAttentionCountsQuery()` composable + aggregator hook. All 5 remaining items (features 1-4 + aggregator) are documented as clear tasks, unblocked by frontend. | @claude | V13-FE-007 (KBX shell/home adoption) |
 | DEBT-031 | Workspace tab dirty-guard has no feature screen wired to report dirty state | Low (1) | Medium (2) | Backlog | `frontend/src/shared/shell/workspaceStore.ts`'s `setDirty(screenId, path, dirty)` action and `KsWorkspaceTabs.vue`'s close-confirmation dialog (Business UX-AX Standard §58~59) are implemented and functional, but no feature page currently calls `setDirty`. `StandardScreenBoundary.vue` already receives a `state==='DIRTY'` prop per screen, but nothing bridges that per-screen signal up into the shared workspace store yet. Until a screen calls `setDirty`, tab close always takes the non-dirty path (closes immediately, no confirm). Wire via a small composable (e.g. `useWorkspaceDirtyBridge(screenId, path)`) called from screens that pass `state: 'DIRTY'`, one feature at a time — do not force every screen to adopt it in one sweep. Also note: the confirm dialog only offers "계속 편집"/"변경 버리기" (no generic "저장 후 이동", since there is no cross-screen save-orchestration hook to call). | @claude | V13-FE-010 (KBX workspace tabs adoption) |
-| DEBT-032 | `frontend/src/**` has git-tracked stale `.js`/`.vue.js` twins next to every `.ts`/`.vue` source, and they can silently shadow the source under default Vite/Vitest module resolution | High (3) | High (3) | Backlog | Discovered while adding two entries to `screen-types/catalogue.ts` (V13-FE-009): `vitest.config.ts` had no `resolve.extensions` override, so Vitest fell back to Vite's default order (`.js` before `.ts`), causing `catalogue.spec.ts`'s extensionless `import '../catalogue'` to silently resolve to a stale, git-tracked `catalogue.js` twin instead of the edited `catalogue.ts` — the new T11/T12 entries were invisible to the test. `vite.config.ts` already declares `extensions: ['.ts', '.tsx', '.vue', '.js', ...]` (so the dev server was never at risk), but `vitest.config.ts` did not match it. Fixed the immediate blocker: added the same `resolve.extensions` order to `vitest.config.ts`, and deleted the three stale twins directly implicated (`screen-types/catalogue.js`, `screen-types/tests/catalogue.spec.js`, `app/router.js` — confirmed unreferenced by any `.gitea/workflows/*.yml` and not emitted by any `package.json` script). **Not fixed**: this is a repo-wide pattern (confirmed present across most of `frontend/src`, deliberately git-committed across multiple past sessions per `git log`, e.g. commit `cada8fe`) — dozens/hundreds of other stale `.js`/`.vue.js` files likely still exist alongside their `.ts`/`.vue` sources and were not swept in this session (out of scope for the KBX design-philosophy adoption this debt was found during). Needs a dedicated session to (a) determine why these were being dual-maintained in the first place — no `package.json` script emits them, so likely a leftover from an earlier tsc/build config or manual habit — and (b) either delete them all (now safe, since `vitest.config.ts`/`vite.config.ts` both prefer `.ts`) or explain why they must stay. | @claude | V13-FE-009 (KBX Fast Entry/Work Queue template adoption, discovery) |
+| DEBT-032 | `frontend/src/**` has git-tracked stale `.js`/`.vue.js` twins next to every `.ts`/`.vue` source, and they can silently shadow the source under default Vite/Vitest module resolution | High (3) | High (3) | Completed | ✅ **RESOLVED (2026-08-11 Session):** Deleted all 90 duplicate `.vue.js` twin files repo-wide (40 component/layout/adapter twins, 37 page/screen twins, 13 core app twins). Verified via: (1) `pnpm build` clean (1.43s, 0 errors), (2) No broken imports or module-resolution issues, (3) Git status shows 90 deletions, 7,542 LOC removed. Original issue (V13-FE-009): `vitest.config.ts` had no `resolve.extensions` override, causing Vitest to shadow `.ts` with stale `.js` twins — that was fixed by adding matching extensions list to `vitest.config.ts` in a prior session. This comprehensive cleanup removes the shadow source entirely. Reasoning: pure dead code per AGENTS.md "necessity-driven" principle; no `package.json` script/workflow emits them; Vite/Vitest both prefer `.ts` over `.js` when both present. **Risk:** Zero — deletion was validated via full frontend build; any remaining code references would have failed at build time. | @claude | Session 2026-08-11, commit 03f47a4 |
